She became a nun after Borgia killed her husband, and she was killed when her convent was destroyed by France during the Italian War of 1494-98.

Biography
Ursula Bonadeo was born in Italy to a noble family, and she married the Barone di Bonadeo in a political marriage. She first met Cardinal Cesare Borgia at the wedding of Lucrezia Sforza and Giovanni Sforza in 1493, when she danced with him. She fell in love with him, as her brutal condottiere husband mistreated her, and she met him again in a confession booth, where they expressed their love for each other. Bonadeo attempted to convince Borgia to not kill her husband, and Borgia promised not to put himself in harm's way. When Borgia did kill her husband, she did not trust her heart anymore, and she wondered whether Borgia loved her, or if he succumbed to the desires of the flesh, and she later went on to reject his love out of guilt. She became a nun at the Convent of Saint Cecilia as "Sister Martha", and she was killed when the French king Charles VIII of France destroyed the convent during his retreat from Rome to France.
